I have recently completely revamped my website. As it took a while, I built the new pages with new page names so the old site could still be up and running. When the new site was finished I republished the old index page as the new one. However I left all the other pages with the new names which I now feel was a mistake. Looking through various threads here to see how to delete old pages so they won't be found by users I'm now not sure what to do for the best:
Should I unpublish the old pages (would I then need to re -submit the new ones to SEs)?
Should I re-name the pages back to the original page names?
Should I redirect the old pages to the new pages and if so, how?
I also want to add a sitemap but obviously need to address the above first.
I'm getting more and more confused and would really appreciate any advice. Thanks for any replies!
